Official forecasts from Russia's Hydrometeorological Center project a daytime high of 15–17°C in Moscow on September 30 under the influence of a high-pressure system, with partly cloudy skies, light northerly winds, and no precipitation expected to allow modest solar warming. Multiple numerical weather models align on this range, consistent with late-September climatology near +17°C, while current observations show temperatures climbing through the mid-teens by midday. Trader consensus at 17°C reflects this model agreement and the low likelihood of significant deviation before sunset. Minor upward or downward shifts remain possible if local station readings or boundary-layer mixing differ from guidance, though substantial changes appear unlikely given the stable synoptic pattern.
